UPHOLSTERY PIPING BAT AND METHOD OF MAKING THE SAME.

' Application filed March 16, 1925. Serial No. 16,079. i

To all whom) it may concern:

Be it known that I, MAURICE J. STAoK, a citizen of the United States,residing at Cohoes, in the county of Albany and Stateof New York, haveinvented certain new and useful Improvements in Upholstery Piping Batsand Methods of; .Maki 1g .the jsan'iey of I which the followingisaspecification.

The invention has for its object to provlde a new and improvedconstruction of and method of manufacturing upholstery "piping battingforuse in upholstering auto'-.

mobile seat backs, cushions, quarter top pads and the like. i

In the now connnonly used methods of manufacturing such batting the sameis" made in continuous lengths andof a width formed by folding arelatively wide sheet 'of batting upon. itself at successive inter-,

vals to provide the desired Width and thickness of said batting. Toprovide desired tensile strength in the batting. cores are laid into thecentral or other folds thereof. such cores consisting of continuouslengths of fabric or paper and when'theflatteris used,

it is usually gummed to hold it to position i and frequently to hold thefolds of the bat together. 'The great'additional expense of manufactureoccasioned by such use voi: :l.a.b-

Jric and paper cores and .;the.inconveniences and ineflicienciesof such'vuse shouldbe readily apparent to those skilled inthe art Lin vwhichsuch battingis'used; A few of'the undesirablev features alluded to arehere mentioned; First the cost of such materials and the labor andexpenses incident to their purchase, storage and use: second, the wasteoccasioned by the necessity of throwing away sections of the battingwhich, by'

fault of machinery or human attention at an luterval 1n the process ofits manufacture,

become unfit for commercial use, it being impractical to remove thecores from such sections and therefore necessary that the whole thereof,including the cotton batting proper which could otherwise be reworkedand used, be thrown away: and third, the

impracticability of the most commonly used paper cores in that theyutterly fail to ac-.

coinplish their intended purpose of roviding tensile strength to thebatting an break from their secured points or some place throughouttheir length upon the first sudden shock in actual use. p

It is therefore. the object offimy present invention to. provide a.constructioneof. -.bat--F':'

ting and method of -.making the sarnein \vhicl1- ;the' {desired tensilestrength is provided bv. use of'a core of the same material of which thebatting is formed, not subject to readybreakage, in the manufacture ofwhich it is unnecessary to employ any mahas taken place.

ment, ally of which will be first fullyu described in the followingdetailed description, then particularly pointed out in the appended.claims, reference being had to the accompanying drawings, iuwhichFigure. 1 is a diagrammatic plan view illustrating the mannerin whichthe batting sheeti istwist foldedat successive intervals .to formthecomplete continuous length of batt1ng,-the manner-of layingsin,the'ysoft rope core being also shown.

i The numeral 9 desi "ates the soft-r core of the batting whieh is madeup of tin same cotton batting.i'n'ate'rial as is the sheeting' 1, whichmay inade mor or less stron according to how vti 'htly the same istwist-formed, and which hasthe quality of not'elongatin'g to anyconsiderable degree 7 under stres es {Of 1156, thereby giving tensilestrength to the, finished batting into the folds of which it. is laidand matted in the manner soon to be e iplained. V

In making up thebatting the soft-rope core 9 is laid such a distancefrom 'the edge of the cotton sheeting l vas to enable the After folderto twist-fold overtheshorterwidth to the side thereof as indicated inFigure 3 of the drawings. 1

gaa ssing the twist-folder. (it being un erstood that the Cottonsheeting is travell' in the direction .of the arrows on Figure 1 thefolded parts are compressed by passing between rollers \2 or beneathroller 2 and over an immovable table as may be found convenient, inpractice (it being understood that apparatus for manufaetu'ring thisbattiii" forms no part of my present invention); N i v erted by theroller or rollers 2 is such as e amo nt of eomprn ion en'- '0 reduce thethickness of the material to the desired degree before the second twist-7 fold is made. 1 Having passed the roller or rollers 2 the material is'v'en a secondtwish foldby the folder 6. he parts will then appear asillustrated inFigure 5, and after p'assin'gthrou'gh the second set ofpresser rolls 3 the part will appear as illustrated in Fired, p,

fter passing the secondset of rolls 3 the third and fourth twist-foldswill-be imarted successively to the material by the olders and 8respectively, the parts then appearingas illustrated in Figures 7 and 8respectively, after which they will ass through the finalpr'esser (rolls4 and the attin be compressed to its final condition as indlc'ated inFigurfe 9 and generally indicated in the drawings by the numeral 10.

As beforews'tatfed tn-seem 9 is in the nature of a soft-rope termed ofthe same cotton battin material of which the batting sheet is ormed andthe strength of the same maybe varied Ia'c'co'rdin to how tightly thematerial from which 1t is formed is twistedto make the same. a a y I Iprefer to. use a twist-formed eore rather than a soft rope of theplaited type'for a purpose soon to b'e ezliplained. By us ng such a horeI have found by aet'u'al test that the finished batting is much stron"er than that formed with paper cores and t e many disadvantages of cost,ready breakage, and rattling of l the batting so equipped is entirelyeliminated. a

By usm'ga soft of the twisted type and laying that rope; with thdirection of ts twist opposed to the directionof the first and the twosuccessive twist-folds accomphshed by the folders 5', 6 and 7, as the,folds mentioned a're made inth'e direction indicated by the, arrows onFigure 3 the effect will be to jsoinewhatunw'r'ap the soft rope corewith the double of facilitating the intermingling'and flattening out ofthe fibres of vthat rope and the causingof-the fibres thereof ,to becometightly enmeshed with those of the fold into which the rope is a laid.The effect ofthis function is so efiicient thatmueh reater tensilestrength is given to thebattlngathanby the of paper cores and fibresbecome so enmeshed that the parts become substantially as one andr'norethan fill the need fora holding medium heretofore answered only bythe more or less undesirable use of the gummed. feature in shell papereore use. Should it become necessary 0 discard a portion of battin inadeby my improved method becauseo .faultyhandhng or similar reasons,wasting of that portion is [unne ry as, o i i of th s ,bij i e i likematerial as the betting, the .whole theref be reworked and reused,

a Beetion of In igure of the drawings batting is illustrated with asection of softrope core projecting therefrom. In Figure 11 isillustrated substantially the manner in which the fibres of the core areunravelled and caused to flatten out and intermingle with the fibres ofthe fold into which the said core is laid.

As stated the use of such core provides batting of greater tensilestrength, which is not open to the objections urged to the use of agummed paper core, viz: occasioning complete wasteaof imperfectuncommercial sections, objectionable rattling and ready breakage underslight shock.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the noveldetails of construction,method of manufacturing and the advantages of my invention will bereadily apparent to those skilled in the art to which it relates.

What I claim is: I

1. Cotton batting of the class descrlbed formed of successively foldinga sheet of fibrous material and having a core of softrope of thetwist-formed type laid in one fold thereof, the twist of said core beingopposed to the direction in which said folds are'made.

2. The method of making cotton batting of the class described whichconsists in laying a core of soft-rope of the twist formed type upon asheet of fibrous materlal and successively folding-that sheet to enfoldsaid core and to provide the desired batting width, the twist of saidcore being opposed to the direction in which said folds are made tocause the same to be partially untwisted by'said folding action and thefibres of the same and those of the sheet being folded to enmesh.

3. The method of making cotton batting of the class described whichconsists in laying a core of soft-rope of the twist-formed type upon asheet of fibrous material, the said sheet and the said core being of thesame material, and successively foldingthatsheet to enfold said core andto provide the de sired batting width, the twist of said core beingopposed to the direction in which said folds are made to cause the sameto be parof the same kind and grade of material.

5. Themethod of making continuous bats which includes the steps oftaking some bat material and twisting it into a rope, laying the rope ona batting strip and folding the strip over the rope as a core whilepermitting the rope to untwist more or less thereb to cause its fibresto rub and interlock with the fibres of the strip.

6. Themethod of making continuous bats which includes the steps oftalking some oat material and twisting it into a re e laying the rope ona batting strip and f0 (1- a ing the 'strip over the rope as a corewhile permitting the rope to untwist more or less thereby to cause itsfibres to rub and interlock with the fibres of. the strip, and applymgflattening pressure to the folded bat to flatten the core.

'7. A continuous bat with a core composed of the same material as thebat loosely twisted into the form of a rope and having its fibresinterlocked with those of the bat proper. I

8. A bat reinforced by a core which has greater tensile strength thanthe bat, said core being composed of fibres adapted to mix with those ofthe bat, said fibres being so loosely interengaged with each other thatthey may be readily picked apart when the bat is reworked.

9. A cotton bat comprising a-body of batting material enclosing asoftrope core of a material suitable to mix with the stock of the bat.

10. A cot on bat comprisin a body of bat material enclosing a core 0%soft loosely twisted rope of a material suitable 'tb mix with the stockof the bat.
